Coupling for double-wall tube DKC d75 mm 015075

The coupler for a double-walled corrugated pipe is used as an element of one-piece pipe joining mechanically. Pipes are joined together with the same diameter, but the rigidity can be different. Using a sealing ring that is worn between the corrugated hollows of the pipe, a degree of tightness of IP55 can be achieved. Fittings are made of polypropylene.
